HyQuest Solutions’ vented hydrostatic pressure sensor VHPS is a programmable submersible level transmitter for measuring water level and temperature in groundwater and surface water. It is low power, robust, and especially designed for use in harsh environments, ensuring longterm measurement stability.
The VHPS provides very accurate results: The sensor is vented and automatically self-compensates for barometric pressure changes, i.e. it eliminates errors up to several inches that can be caused by pressure changes. Additionally temperature compensation is calculated from the measured water temperature. Capillary is integrated into the sensor cable with moisture ﬁlter at the open end (optional). The fast reacting membrane technology of the VHPS provides long-term measurement stability.
Special attention was paid to robustness: The pressure cell is resistant to physical force (3 x burst pressure). The VHPS can be deployed in a variety of environments including natural and grey waters, drinkable water, saltwater and oil polluted waters. You can choose between stainless steel and titanium enclosures, and between three types of cable materials.
Equipped with an SDI-12 interface, the VHPS is easily connected to data loggers, and can be conﬁgured using standard SDI-12 commands. In addition, SDI-12 is the best choice for low-power applications.
- Very accurate readings thanks to
- Barometric pressure compensation (venting)
- Temperature compensation (calculated)
- Digital data transfer to data logger
- Robust design
- Wide application range
- Low-power sensor
- SDI-12 interface
Its robustness makes the VHPS an ideal sensor for monitoring water level in surface and groundwater, including:
- Sloping point bars or embankments
- Pipes and bore holes with Ø > 1
- Dams, weirs, irrigation systems
- Waterways that occasionally ice over
- Brackish water, saltwater
- Retention basins
